I have a growing table storing time series data, 500M entries now, and 200K new records every day. The total size is around 15GB for now.
My clients are querying the table via a PHP script mostly, and the size of the result set is around 10K records (not very large).
select * from T where timestamp > X and timestamp < Y and additionFilters
And I want this operation cheap.
Currently my table is hosting in Postgres 7, on a single 16G memory Box, and I would love to see some good suggestion for me to host this in low cost and also allow me to scale up for performance if needed.
The table serves:
1. Query: 90%
2. Insert: 9.9%
2. Update: 0.1% <-- very rare.

PostgreSQL 9.2 supports partitioning and partial indexes. If there are a few hot partitions, and you can put those partitions or their indexes on a solid state disk, you should be able to run rings around your current configuration.
There may or may not be a low cost, scalable option. It depends on what low cost and scalable mean to you.
